Martin Lewis warned people 'not to panic' as customers rushed to submit meter readings before Friday's price jump.
Households are submitting meter readings for gas and electricity to their supplier today to show exactly how much energy they have used ahead of Ofgem's price cap increasing from April 1. This will prevent firms from estimating usage and potentially charging for energy used before April 1 at a higher rate.
Households will see the biggest rise in the cost of energy in living memory from Friday when bills increase by 54%, or almost £700, to just under £2,000 a year. However, Martin has urged people not to worry if they aren't able to get a meter reading today.

Martin tweeted: "To reiterate again you DON'T need to give a meter reading today if you're on a fixed deal or are in Northern Ireland, or anyone else whose tariff is not on the price cap.
"And again if on smart/prepay just take a pic of your meter, no need to submit."
He added: "If you can't get to do a meter reading today, do it tomorrow, or Sunday, or Monday.
"The nearer to today you do it the less chance of misestimates, so don't panic about missing it (either through your own or the firm's issue) just get it in as soon as you can."
